COMBINED SLATE-PENCIL SHARPENER AND SPONGE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 300,735, dated June 17, 1884.

Application filed September 1, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE O. PRrcE, GEORGE WV. F. COOK, and WALLACE 0. PRICE, all citizens of the United States, and residing in the city'and county of San Francisco, and State of California, have invented a new and useful Combined Slate-Pencil Sharpener and Slate-Sponge Holder, of which the following is a specification.

Our invention relates to combined slatepencil sharpeners and slate-sponges which are arranged for attachment to a slate by means of any suitable string or ribbon. It will be fully understood by reference to the accompanying drawings, in which Figure 1 is a perspective View; Fig. 2, a top edge view; Fig. 3, a side elevation showing the spongeclamp. Fig. 4 is a cross-section cut through the dotted lines a a shown in Fig. 1. Fig. 5 is a longitudinal sectional elevation showing the same out through the center. Fig. 6 is a detail view of the cutters.

XVe form the holder A of wood, vulcanized rubber, metal, or other suitable material, to form a neat and convenient implement of use, somewhat similar in finish to the Faber wooden rubber-holder.

We form the dust-chamber B, and place the cutters D and O in the position shown, with the beveled cutting-edges sharpened, so as to form the point of the pencil as it is turned by the fingers in the usual way of operating slate- I pencil sharpeners of that class.

XVe form the concave or recess E to receive the sponge F, which is firmly pressed in the same, and the clamp G closed upon it, the points H passing through the openings L and penetrating and holding the sponge firmly. The sponge may be wired in with a light copper wire; but we have found the clamp G the best and neatest attachment for holding the same and allowing it to be taken out and replaced readily. This clamp may be made of ordinary sheet metal and held by the screws; or it may be formed of spring metal and allowed to spring to its place and clamp the sponge by the force of the spring.

We form the hole K to receive a string or ribbon for attaching to the slate, rounding the edges and finishing them smoothly. This renders it very handy for use in sharpening pencils and washing the slate.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

A combined pencil-sharpener and spongeholder, consisting of the holder A, having a space, B, the cutters D O, secured in place therein, the space E for the sponge F, and the described means for holding the sponge in 60 place, all substantially as described.
